KEMET SH-202 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The KEMET SH-202 is a 2-line common mode choke designed for power line filtering applications. This through-hole component operates at 1.5 µH inductance at 100 kHz with a maximum current rating of 3A and 20 mOhm DC resistance. The part is active in production status and ROHS3 compliant. Substitute parts are identified to provide alternative inductance values while maintaining compatibility with the same mechanical footprint, current rating, and electrical operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KEMET SH-202 are qualified based on the following criteria:

Mechanical Compatibility: All substitute parts maintain identical mounting type (through hole), package configuration (vertical, 4 PC pin), and physical dimensions (0.492" L x 0.394" W x 0.472" H maximum).

Electrical Compatibility: All substitute parts share the same current rating (3A maximum), voltage rating (150V DC), and operating temperature range (-25°C to 80°C).

Functional Compatibility: All substitute parts are 2-line common mode chokes within the KEMET SH series designed for power line filtering applications.

Variable Parameter: Inductance value at 100 kHz differs among substitute parts. The SH-202 provides 1.5 µH, while substitutes offer 0.35 µH (SH-101) and 0.5 µH (SH-201). DC resistance values vary between 16 mOhm and 20 mOhm across the group.

Substitution is valid when the application circuit tolerates the specified inductance and DC resistance values of the alternative part.

Parameter Comparison

Engineering Selection Recommendations

All three parts (SH-202, SH-101, SH-201) are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by the required inductance value for the application circuit.

SH-202 (1.5 µH): Select when 1.5 µH inductance at 100 kHz is specified in the circuit design. DC resistance is 20 mOhm maximum.

SH-101 (0.35 µH): Select when 0.35 µH inductance at 100 kHz is required. This part offers lower DC resistance at 16 mOhm maximum, reducing power dissipation in applications tolerating lower inductance values.

SH-201 (0.5 µH): Select when 0.5 µH inductance at 100 kHz is required. This part also features 16 mOhm maximum DC resistance.

All parts share identical mechanical footprints, current ratings (3A), voltage ratings (150V DC), and operating temperature ranges (-25°C to 80°C), ensuring direct board-level compatibility when inductance requirements are met.

Frequently Asked Questions (FAQ)

Q: Can SH-101 or SH-201 be used as direct replacements for SH-202?

A: Direct replacement is possible only if the application circuit tolerates the lower inductance values. SH-101 provides 0.35 µH (versus 1.5 µH in SH-202), and SH-201 provides 0.5 µH. The mechanical footprint and current rating are identical, but inductance is a critical functional parameter that must match circuit requirements.

Q: What is the difference in DC resistance between these parts?

A: SH-202 has a maximum DC resistance of 20 mOhm. Both SH-101 and SH-201 have maximum DC resistance of 16 mOhm. Lower DC resistance reduces power dissipation and heat generation in the component.

Q: Are all three parts through-hole components with the same pin configuration?

A: Yes. All three parts use through-hole mounting with a vertical, 4 PC pin package configuration. Physical dimensions are identical: 0.492" L x 0.394" W with a maximum height of 0.472".

Q: Do these parts have the same voltage and temperature ratings?

A: Yes. All three parts are rated for 150V DC and operate across the temperature range of -25°C to 80°C.

Q: Are all parts ROHS3 compliant?

A: Yes. SH-202, SH-101, and SH-201 are all ROHS3 compliant and REACH unaffected.

Q: What determines whether I should choose SH-101, SH-201, or SH-202?

A: The primary selection criterion is the required inductance value at 100 kHz. Choose SH-202 for 1.5 µH, SH-201 for 0.5 µH, or SH-101 for 0.35 µH. All other electrical and mechanical parameters are compatible across the group.
